The Browns have just five measly wins against the Steelers since 1999. Your average teenager in Cleveland knows nothing but beatdowns by Pittsburgh, twice a year, since the beginning of time.

When a blood feud becomes this one-sided, there's little for fans to latch onto. Both sides must feel the heat. That's why Browns-Steelers -- and a few other historically classic showdowns -- don't make my list of the top rivalries for 2013.

Here are the six that do:

6. Green Bay Packers-Chicago Bears

This would rank higher, but it's hard to take the Bears seriously until they knock the Packers off their high horse. A general, psychic mistrust of Chicago's franchise stems from its inability to go toe-to-toe with Green Bay. This sneaks in at No. 6 because new coach Marc Trestman brings hope for a Bears offense that, for years, has been a coma-inducing affair.

4. New England Patriots-New York Jets

I'm giving this one more year. As long as Rex Ryan roams Florham Park -- wringing his hands over the mere existence of Bill Belichick -- this remains must-see TV. Granted, Gang Green is a messy disaster, but this showdown remains sexy because of Bill's history with both teams; because of Tom Brady's acknowledged hatred of the Jets; and because even when New York struggles, it knows enough to float "butt fumble" into the public lexicon.

3. Baltimore Ravens-Steelers

Everything Browns-Steelers once was has been swallowed up and replaced by this engaging, ugly relationship between Pittsburgh and Baltimore.

2t. Denver Broncos-Patriots/Ravens-Patriots/Ravens-Broncos

I don't relish ties, but this three-way timebomb arguably could chew up half the list. Whoever emerges on top should win the AFC.

1. Seattle Seahawks-San Francisco 49ers

In quick order, this has become a classic. There's a collective sense these two will decide the NFC. Last year's meetings were doozies: A rugged 13-6 win by the 49ers in Week 7, answered by the Seahawks' 42-13 hammer-drop in Week 16. I'll never forget that night. Stationed in a Los Angeles sports bar, I watched as a perspiring, cherry-red-sweater-vest-wearing 49ers fan screamed at the top of his lungs at Russell Wilson: "Make it stop! MAKE. IT. STOP."
